Abstract:
Objective:To explore the application value of cinematic rendering reconstruction technology in laparoscopic resection of giant adrenal tumors.Methods:As many as 21 patients with large adrenal tumors who underwent laparoscopic resection in Yongchuan Hospital Affiliated to Chongqing Medical University from January 2021 to January 2024 were retrospectively analyzed, with a median age of 54.0 (40.5, 58.0) years and a median tumor diameter of 7.3 (6.8, 8.8) cm. All patients underwent preoperative cinematic rendering 3D reconstruction imaging. All patients underwent enhanced CT scans. Their CT images were three-dimensionally reconstructed on the post-processing workstation platform. By changing image perspectives, adjusting the visualization of organs or blood vessels, and using physical volume rendering, real-shadow-rendered images were obtained. With these images, surgeons can intuitively understand important preoperative information, like the relationship between the tumor and surrounding organs and the path of tumor-feeding blood vessels, for preoperative planning. Following thorough preoperative preparation, laparoscopic transabdominal resection was performed. During surgery, 20 tumors were found to be located in the adrenal gland, and 1 in the retroperitoneum, with 13 on the left side and 8 on the right side. Preoperative cinematic rendering 3D imaging was consistent with intraoperative findings.Results:All 21 patients underwent successful surgeries, with an average operation time of (199.0±95.3) minutes, a median blood loss of 220 (150, 500) ml, and a median blood transfusion volume of 200 (150, 400) ml. No significant damage of vital organs or major blood vessels occurred, and there were no case of conversion to open surgery.Conclusions:For retroperitoneal giant adrenal tumors, utilizing cinematic rendering 3D reconstruction imaging enables a comprehensive understanding of the relationship between the tumor and surrounding organs and vessels preoperatively. This approach can reduce intraoperative bleeding and collateral injuries, improve the success rate of laparoscopic resection, and enhance overall surgical safety.
